Overall the Pure Gym i use (Kingston Milton Keynes) is good. Good space,loads of plates and racks, bars, machines etc..The let downs are: the amount of lazy gym goers that leave their station as if they're still working out i.e. fully loaded bar and just walk off. The misuse of equipment like dropping empty or light bars, smashing the safety bars with a similar loaded bar, again for no reason other than the effect of sounding like they're going 'heavy'.
I realise it's a business and if the local yoofs wanna come and scroll for an hour then that's their entitlement. Apart from that it's ok. I think that the gym staff could also intervene when an inexperienced lifter is clearly lifting more than they're capable, especially when you see guys prawn backing a deadlift that is never leaving the floor.
